Meet Boston Dynamic's BigDog - a whole lot cooler and more advanced than that stupid Japanese walking toaster, what an asimo:
According to the the website, BigDog runs on a two-stroke gasoline engine which powers its hydraulic system, it has an on-board computer that controls locomotion, servos, the legs and handles a wide variety of sensors. So far, BigDog has trotted at 3.3 mph, climbed a 35 degree slope and carried a 120 lb load.
It needs a muffler, or a quieter power plant - but can you see this thing trotting along with a squad of soldiers? Or even carrying your camping gear on an overnight hike? How about a train of these things carrying tourists on their backs down to the bottom of the Grand Canyon and back?
No jetpacks yet - still, it's starting to feel a lot like the 21st Century.
